The Aroma Shooter Wearable blasts scents while you watch videos

One of the missing pieces of puzzle for VR is scent, but at CES 2024 in Las Vegas, Japanese startup Aromajoin showed off a wearable that may be up to the task. Simply dubbed Aroma Shooter Wearable, this neckband houses six replaceable scent cartridges, and it's controlled by a mobile device or PC over Bluetooth, Wi-Fi or USB. The product is still in its early days, and the Kyoto-based company is targeting developers and business clients, who can pick from a library of "hundreds" of scents — or even custom scents from, say, fragrance brands — to suit their needs.

In Aromajoin's demo, a video player app was programmed to cycle through those six scents — lavender, blueberry, shampoo, caramel, smoke and fresh cut grass — to match the six scenes in the short clip. Even though I was watching what was otherwise a regular video on an iPad, the scent definitely boosted the immersion, and I can imagine this making an even bigger impact when paired with VR.

For the purpose of CES, Aromajoin only had one demo on hand, but the app did show how one could program any video clip to trigger certain cartridges — yes, you can have multiple scents at any instance — at certain times. You can also adjust the intensity of each scent, which came in handy as I found the grass smell to be a bit too strong at first. As for the neckband itself, it weighs around 300 grams, but I didn't feel much burden thanks to its ergonomic shape around my collarbone area.

Aromajoin plans to launch its Aroma Shooter Wearable via crowdfunding this May, with shipment expected by the end of this year. Target price for the device is around $350, with each scent cartridge likely to cost around $30. Each cartridge should last for around 3,000 shots or up to three months, though this depends on the intensity and the nature of each mixture.

Aromajoin also applied the same video demo to a larger setup dubbed Aroma Speaker 60, which is aimed at retailers, cinemas and VR arcades. As the model name implies, this pair of tower can be equipped with up to 60 scents, with each of the 10 magazines housing six scents, thus supporting a wider range of scenes or use cases. The Aroma Speaker 60 will also be launched via crowdfunding, but expect it to cost a lot more than its neckband counterpart.
